Although Lu Zhou does not understand economics, in a place like Princeton, any subject that has a little relationship with mathematics has more or less a relationship with people who study mathematics. Especially things like economics. Either a new social production relationship is born or the scope of human civilization is further expanded, otherwise it is difficult to create novel theories through traditional theoretical research methods. Therefore, to make outstanding research results, mathematics can be said to be the only way out for modern economists. Although this situation has been criticized by traditional economists for showing off digital games, it has indeed helped the industry solve the problem of countless doctoral students' graduation and employment. In fact, in the field of theory, it has grown savagely for so many years. Mathematics is a bottomless mine for any computing science. Can you dig out valuable things? It depends on how scholars in other fields use them. And improve those mathematical tools that have been refined from numerous problems, and integrate them into their own subject areas. Therefore, although Lu Zhou is not particularly interested in economics, whenever he appears in the cafe on the first floor of the Princeton Institute of Technology at 3 pm, occasionally, professors engaged in economics research take the initiative to talk to him, and Talk to him about mathematical problems that are not so difficult. After staying in Princeton for so many years, Lu Zhou has dealt with the economic bull who can't count both hands. Not to mention the big names who have won the Nobel Prize, and even the editors of the top magazines in Nature and Science have nothing to do with him. Anyone with normal IQ will not risk offending such a big guy, and get a master's diploma and degree certificate ... As for why Lu Zhou must be the corresponding author ... it's not that he cares The corresponding author of a dissertation simply did not want Xiao Tong's mentor to take advantage of him. Although still a little worried, but seeing the omnipotent brother said so, Xiaotong no longer insisted, and asked his parents about his condition and his recent good or bad, then he was too hungry in Luzhou Urged, hung up on the phone reluctantly. After closing the laptop, stretched out a lazy land boat, pulled out the phone and ordered a takeaway, then opened Xiaotong's unfinished paper, and looked at it line by line. "Let me see ... seems a bit interesting?" Although he doesn't know much about Bewley's model, the part involving mathematics is to him no different from the math work of elementary school students. After all, no matter how complicated the model is, it can't be more complicated and chaotic than a plasma turbulent system. And even the NS equation and the model of plasma turbulence can solve these two world-class problems. A Bewley model is not even qualified to raise shoes for him. For functional analysis, if he considers himself second, no one can call it first. However, occasionally thinking about some simple problems is also helpful for his research. Anyway, the takeaway has not been delivered yet, and idle is also idle, right when you feel relaxed. Hold the ballpoint pen in your right hand and put the left hand on the keyboard, and quickly pass the information in the attachment. The nib pinched at the fingertips of Luzhou is like a flying wheel, and runs over a stream of smooth and neat marks from the paper. "Although it is a bit simple, it is indeed an interesting mathematical problem ... Who talked to me when I was in Princeton? It's a bit difficult to remember." "... Why use the Lagrange multiplier method? Solve every step in the optimization process? "When calculating a certain block, the pen tip in Lu Zhoushu paused for a few seconds. However, it was only a few seconds. "You can use the endogenous grid method ..." muttered to himself, Lu Zhou crossed out the previous line of steps and re-written a line of calculations. "The endogenous grid method is also a bit troublesome. Directly optimizing the original mathematical model can save at least 20% of the tedious calculations ... probably 25%." This kind of problem is really not a problem. The gushing inspiration broke the city wall before the finish line in an instant. After writing the last line of calculations, Lu Zhou leaned back on the office chair, slightly lowered the screen of the notebook, and directed the front camera to his own draft paper. "Xiao Ai, help me organize it." "By referring to the Bewley model, compile a new algorithm for my new model." Xiao Ai: [Received ~ give Xiao Ai! (?? ▽?)] Almost as fast as Lu Zhou's page turning, Xiao Ai, who completed the scan of the calculation steps in the shortest time, quickly organized the entire mathematical model, and there may be problems or typos. The place of the class is marked out and presented in front of Lu Zhou. Lu Zhou simply glanced and confirmed that there were no problems in the marked area, then nodded towards the computer. Soon the data was uploaded to the quantum computer located in the underground of Jinling Institute of Advanced Research. Almost a few seconds after the data transmission was completed, the feedback data was transmitted from the quantum computer. Xiao Ai: [Completed algorithm compilation! (??????) ?? Xiao Ai: [Compared with 12777 sets of random parameters, the numerical calculation results of the improved mathematical model are basically consistent with the original model, the dispersion is reduced by 13%, and the computing efficiency is increased by 21%. ? (^? ^ )] What the dispersion of the calculated result means is not clear to him, but the 21% improvement in computational efficiency is basically in line with his expected result. Speaking of using a quantum computer to check the master's thesis, will there be a feeling of hitting flies with a cannon? Nevermind. Who wants him to have only one sister? Not to mention that the electricity bill in the province of Jiangsu is not worth the money ... Thinking of this, Lu Zhou looked at the computer and continued to order. "Help me edit an email and send the algorithm and mathematical model together." Xiao Ai: [Good master! (??????) ??] Seeing the emoji behind the string of bubbles, Lu Zhou suddenly remembered something, and then he said, "Yes, remember not to put your emoji and emoticons in the email, Just send the mail normally. "Xiao Ai: [Σ (っ ° Д °;) っ] Lu Zhou:" ...? "Although I didn't quite understand what Xiao Ai's expression meant, but Lu Zhou It is not hoped that because of a few emoticons or off-line expression packs, he would destroy the image of his tall, handsome, smart and reliable brother in the mind of his sister. It took almost five minutes for the email to go out. He received a reply from Xiaotong in his mailbox. Although the content of the email is very short, it is even as short as three characters ... [? ? ? ] Seeing these three question marks, Lu Zhou's mouth evoked a smug smile. Come to think of it, Xiaotong didn't expect it, and it only took him an hour to solve such a "difficult" problem. "Speaking of it, it's been an hour. Why hasn't the takeaway I ordered yet?" After rubbing his belly, Lu Zhou took out his cell phone and was about to make a phone call to the delivery man. It was signed ten minutes ago. Lying down? Who took my takeaway? He was so involved in solving the problem just now that he didn't even notice the reminder on the phone. Just as Lu Zhou was aggressive, the office door knocked three times, and then Wang Peng, carrying the packing box, came in. "Your rice with yellow pheasant chicken," put the plastic bag with the packing box on the table, and Wang Peng sighed. "Let's discuss it? I'll buy it for you. Can we order it later?" The take-out was purely to increase the difficulty of our work. "" Everyone is hungry, it is easy to get things done. "He reached out and took out the packing box from the plastic bag. Why did you send it? "Wang Peng:" I will be safe to send. "Lu Zhou:" This means ~ EbookFREE.me ~ My security level has increased again? "Wang Peng hesitated, and clicked Look down. "Well." There's nothing to hide in itself. Just like when the research on controllable fusion entered a critical stage, the local military region directly transferred a company to be responsible for the security of his place of residence, and it was not adjusted to normal levels until the Pangu fusion reactor was connected to the power grid. Although it is not as exaggerated as the research on controllable fusion at the time, and the international form is not as severe as it was then, carbon-based chips are after all related to the future of the domestic semiconductor industry. It is right to be careful. Hearing this "um", Lu Zhouxuan's hand with chopsticks stopped and he silently glanced at Wang Peng. Just when Wang Peng was a little confused by this look, Lu Zhou said with a cough. "... You didn't do that ... taste a bit of something, right?" Although there is no such thing as cleanliness, or maybe it is a bit cleanliness ... Unless it ’s okay to eat at the table, other people have touched it. The food he eats, both psychologically and physically. "How is it possible?" I was stunned by Lu Zhou's words, and Wang Peng coughed slowly before he came over. "It's all the age, and there is no such thing as drug test. But you don't have to worry about hygiene. Dr. Yan has done a simple test, there must be no problem in health. "Lu Zhou:" ... "MMP! It turned out that I took my takeaway and went to do a test. I said how could it be so slow! He almost made a bad review backhand. Only when he heard Wang Peng's explanation, Lu Zhou became more tangled. Before passing it, Dr. Yan's hand passed ... This guy has a previous record ... Lu Zhou still remembers that this product stole his cola a year ago. No, it should be said that Mingqiang used to drink. Thinking of this, looking at the take-out Luzhou, I couldn't help but be lost in thought. To eat or not to eat? Really tangled ...
